VIOLIN PEG.

Application filed April 5,

To @ZZ #uf/funn it' may concern:

Be it lrnown that I, .loirN LiNns'rnoM, a citizen of 'the United States,residing at Henderson, in the county of Henderson and State of Kentucky,have invented certain new and useful Improvements in Violin Pegs, ofwhich the following is a specification, reference 1neing had to theaccompanying drawings.

This invention relates to pegs more partieularly de hned for violins butadaptable to ed instruments, such as violinother str.A celles, guitars,banjos, and the like, and one et the objects of the invention is toprovide a peg of this character which will positively hold against therotative strain applied to it by the tension of the string.

Another object in this connection is to provide means whereby thefrictional resistance to the reverse rotation of the peg may beincreased or decreased as desired. Still another object is to providemeans whereby the string which, as usual, paes through a hole in thepeg, may be positively engaged so that short strings, incapable of beingwrapped around the peg, may be utilized and positively engaged with thepeg.

Other objects have to do with the details of construction as will appearmore fullw7 hereinafter.

lMy invention is illustrated in the aecompanying drawings, whereinFigure 1 is a face view of a violin head showing my tightening peg insection;

Figure 2 is a section on the line 2-2 of Fig. 1;

Figure 3 is a like view to Figure 1, but showing a modification of thetightening Peil? Figure 4 is a fragmentary perspective view of theconstruction shown in Figure 3;

liigurc is a section on the line 5 5 of Figure 1 Referring to Figure l.l() designates the head of the violin of the usual character andslotted, as at 1.1. The body of the violin is not shown, as it forms nopart of this invention. The peg in Figure 1 consists of a metallic pin12 which at one end has a. head 13 whereby the pin may be rotated. Thepin is hollow, as at 15, and has a diainetrically extending opening 14for the violin string. Entering one end of the peg 12 opposite the head13 is ascrew 16 having a head 17 nicked for the application of 1922.serial No. 549,713.

a screw-driver or wrench. At the head end of the pin or peg 12 andbetween the violin head 1() and the head 13 are disposed a pair ofwashers 18 and 19, the washer 18 being .slightly concave-convex ordished and bearing against washer 19, which in turn bears against theedge face of head 10. The sleeve 2O is disposed over pin 12 and forms abushA ing therefor and holds it in concentric relation to the holethrough which it passes.

Between the opposite edge face of the violin head 1() and the screw head17 is disposed a washer 21 bearing Hat against the edge face of the head10, and bearing on this washer is a coiled volute spring 22. A smallwasher 21il bears against the small end of the spring 22 and the head 17bears against this washer 21, Extending longitudinally through the head13 and through this end of the hollow peg 12 is a screw 23 having a head23L nieked for engagement by a. screw-driver, the extremity of thisscrew 23 being reduced' and intersecting the opening 14 so as to bindthe string within this opening and act as a set screw for this string.This permits a short string to be used which could not be wrapped aroundthe pin.

In the use of this device, the screw 16 is initially tightened up astight as possible and then is turned back one-half a revolution in orderto give the spring 22 a certain amount of play. Of course, where a shortlength string is to be used, itl is passed through the opening 14, thescrew 23 being turned outward a few turns, Then the screw 23 istightened up and the string will be held tightly. The washer 18 isannular in form for the passage of the peg and loosely surrounds thesame and has a notch 18a, while the peg has a lug which extends intothis notch so that this washer 18 is held for rotation with the peg, asshown in Figure Si. 'lhe washer 19 hears against thc edge face of thehead and does not rot-ate with the peg.

lith this construction, the spring 22 will cause such friction betweenthe washers 18 and 19, between the washer 19 and the side edge of thehead 10, and between the washer 21 and the side edge of the head 10 thatthe peg will be held in any adjusted position, while at the same time itis relatively easy to rotate the peg. This friction resisting anyreverse movement of the peg may be in- Cil creased by setting up thescrew i6 and, of course, it may be relieved by releasing the screw 1G.

In Figures 3 and 4, I show a slightly modiiied forni of the inventionwhich, however, embodies the same principle as the device shown inFigure l. ln this figure, the numeral l designates the head oi theviolin, as before, and l1 the longitudinal slot in the head.intersecting this slot is the hollow `or tubular pin 25 formed with theopening 2G for the passage of the string. One end of the peg is formedwith a worm gear wheel 27 which constitutes a head whereby the peg maybe turned and the peg is interiorly screw-threaded at this end for thepassage oi' a screw 28 having a head 29. This screw 28 intersects thestring passage 26 so that when this screw 28 is turned home it will bindthe string in the hole 26. Disposed against the edge tace of the head isa plate 30'which is approximately square in form and has a ringer 31,this plate having outwardly projecting lugs forming bear-ings 'for thesupport of the usual threaded key 32 whereby the peg may be rotated. Theopposite end of the peg is interorly screw-threaded for the reception ofa screw 33, the head o'l' this screw vbearing against a washer 34, whichin turn bears against a volute spring 35, in turn bearing against awasher 37. ln other words7 the construction at this end of the peg isprecisely similar to that illustrated in Figure l. The i'ngervorindicator 32, should the performer neglect to tighten the screwproperly, will strike the neighboring pegv 38 and plate 30 cannot,therefore, turn around. The plate permits this ldevice to be applied ytoa violin head without the necessity of passing screws through the plate30 into the violin head, inasmuch as the finger 3l. bearing against thepeg 38 will prevent any rotation oi: the plate 30. lilith thisconstruction, the E string can be tightened l/lOO part of an inch oreven less rlhe device shown in Figure 3 is best adapted for children, asby this means very little strength is required to turn the peg.

l. In a musical instrument, a tension head and a string peg thereforhaving a passage for a string, the string peg being hollow andintericrly screw-threaded, a head for the peg whereby the peg 'may berotated having an opening aligning with the screw-threaded bore off thepeg, and a screw extending through and engaging the screw-threads of thepeg and intersecting said passage.

n n/sense i2. ,ln a musical instrument, a tension head and a string pegtherefor having a passage 'for a string, the peg having a screw-threadedbore intersecting said passage and having a head at one end, whereby thepeg may be rotated, and a screw extending longitudinally through theheaded end oi' the pin and engaging said bore and intersecting saidpassage.

3. A tension head for musica-l instruments having a longitudinallyextending slot, a metal peg passing through the head and intersecting'the slot, one end of the peg having a head, the opposite end beinginteriorly screw-threaded, a washer concentric to the peg and bearingagainst one face of the instrument head7 a concavo-convex washer looselymounted on the peg to rotate therewith and concentric thereto andbearingat its edges against the iirst named washer, a screw engaging theinterior screw-threads of the opposite end of the peg, a washer bearingagainst the side face of the instrument head adjacent said screw, and acoiled spring disposed between the screw head and said washer.

Il. A tensioning head for musical instruments having a longitudinallyextending slot, a metallic pin passing transversely through the hea-dand intersecting the slot7 the pin having a diametrically extending holedisposed within the slot, one end oi the pin having a head and the pinbeing interiorly screw-threaded, a screw engaging the interiorscrew-threads and having such a length that the extremity of the screwwill intersect the string opening in the peg.

5. A tensioning head for musical instruments having a longitudinallyextending slot, a peg passing transversely through the head andintersecting said slot, the peg having an opening for the passage oi astring and having at one end a head, the opposite end of the peg beinginteriorly screwthreaded, a conczwo-conveny washer mounted upon the pegat the headed end thereof 'for rotation with the peg, a second washersurrounding the peg and against which the rst named washer bears, abushing surrounding the peg, a screw engaging the interior screw-threadsat the opposite end of the peg and having a head, a pair o'f washersmounted upon the screw and one engaging the side `l'ace oi theinstrument board. and volute spring disposed between the washers.
